Evaluating usability of cross-platform smartphone applications

The computing power of smartphones is increasing as time goes. However, the proliferation of multiple different types of operating platforms affected interoperable smartphone applications development. Thus, the cross-platform development tools are coined. Literature showed that smartphone applications developed with the native platforms have better user experience than the cross-platform counterparts. However, comparative evaluation of usability of cross-platform applications on the deployment platforms is not studied yet. In this work, we evaluated usability of a crossword puzzle developed with PhoneGap on Android, Windows Phone, and BlackBerry. The evaluation was conducted focusing on the developer's adaptation effort to native platforms and the end users. Thus, we observed that usability of the cross-platform crossword puzzle is unaffected on the respective native platforms and the SDKs require only minimal configuration effort. In addition, we observed the prospect of HTML5 and related web technologies as our future work towards evaluating and enhancing usability in composing REST-based services for smartphone applications

Agile methods in Ethiopia : an empirical study

This paper provides empirical evidence of agile method adoption in smaller companies in Ethiopia. Agile methods are emerging as best practice for software development in the global north. So, is there evidence that agile methods are being used in Ethiopia? A Grounded Theory approach was adopted using face-to-face interviews with 17 software professionals from 7 software companies, which were selected by using a snowball sampling technique. The interviews were semi-structured and open-ended and have been audio-recorded and transcribed. Participants in the study identified the importance of agile principles, values and practices. Agile practices are used to address issues with requirements and to encourage user participation. However, it was discovered that the companies in the study were conducting software projects for government clients that mandate substantial documentation with elaborate staged approval procedures, using fixed price contracts with predefined delivery schedules
